Abstract: An applicator for highly viscous materials such as dental filling materials has a housing and a first and second jamming element positioned spaced from one another in a longitudinal direction in the housing. A coupling rod is connected to the second jamming element. A piston rod is supported in the housing. An actuating element is positioned at the housing and connected to the piston rod for moving the piston rod in a forward direction from an inactive position into a working position, and in a rearward direction from the working position into the inactive position. The first jamming element is jammed, when the actuating element actuates the piston rod in the forward direction, and is moved with the piston rod in the forward direction. The second jamming element is jammed by a spring force in the rearward direction so as to rest at the housing, when the actuating element actuates the piston rod in the forward direction. The actuating element, when moving the piston rod in the rearward direction, acts on the coupling rod for releasing the second jamming element.

Title: Gas phase alkylation-liquid transalkylation process
Inventor: GHOSH ASHIM KUMAR
IPC: C07C15/073
Filed: 1998-04-09
Granted: 2009-01-27
Abstract: Process for the production of ethylbenzene by alkylation over a silicalite alkylation catalyst with the subsequent transalkylation of diethylbenzene with the alkylation catalyst and conditions selected to retard xylene production and also heavies production. A  feedstock containing benzene and ethylene is applied to a multi-stage alkylation reaction zone having a plurality of series-connected catalyst beds containing a pentasil molecular sieve alkylation catalyst which is silicalite of a predominantly monoclinic symmetry having a silica/alumina ratio of at least 275. The feedstock is supplied to the alkylation reaction zone to cause gas-phase ethylation of benzene at a flow rate to provide a space velocity of benzene over the catalyst to produce a xylene concentration in the product of about 600 ppm or less based upon the ethylbenzene content. Periodically the space velocity may be increased to a value which is greater than the space velocity associated with a minimum concentration of diethylbenzene in the alkylation product such that diethylbenzene production is enhanced while minimizing any attendant transalkylation reactions within the alkylation reaction zone. This is accompanied by a relatively low xylene content in the product, specifically no more than 600 ppm based upon the ethylbenzene in the product. The output from the alkylation reactor is applied to an intermediate recovery zone for the separation and recovery of ethylbenzene with the recovery of a polyalkylated aromatic component which is supplied along with benzene to a transalkylation reaction zone where the polyalkylated aromatic fraction is subject to disproportionation to provide a reduced diethylbenzene content and an enhanced ethylbenzene content.  A specific monoclinic silicalite alkylation catalyst has a silica/alumina ratio of at least 300 and has a crystal size of less than one micron.

IPC: G01V1/28
Filed: 1997-11-12
Granted: 2006-02-28
Abstract: The present invention is directed generally toward a method of processing seismic data so as to provide improved quantification and visualization of subtle seismic thin bed tuning effects and other sorts of lateral rock discontinuties A reflection from a thin bed has a characteristic expression in the frequency domain that is indicative of the thickness of the bed: the reflection has a periodic sequence of notches in its amplitude spectrum, said notches being spaced a distance apart that is inversely proportional to the temporal thickness of the thin bed. Further, this characteristic expression may be used to track thin bed reflections through a 3-D volume and estimate their thicknesses and lateral extent. The usefulness of this invention is enhanced by a novel method of frequency domain whitening that emphasizes the geologic information present within the spectrum. Although the present invention is preferentially applied to a 3-D seismic volume, it is alternatively applied to any collection of spatially related seismic traces.
